DFIT Interpretation Course, SAGA Wisdom

This course covers the DFIT interpretation procedure from the paper URTeC-2019-123. The procedure was developed as part of a collaborative industry study sponsored by a group of six operators and one service company. It is the latest course offered by SAGA Wisdom,available to SAGA Wisdom subscribers.

Sealed Wellbore Pressure Monitoring (SWPM) and Calibrated Fracture Modeling: The Next Step in Unconventional Completions Optimization

Well Data Labs and ResFrac collaborated with Devon Energy is demonstrate an automated workflow for calibrating ResFrac models to Sealed Wellbore Pressure Monitoring (SWPM) data from HFTS 1 Phase 3 refrac project in the Eagle Ford. The workflow we followed was the same as that in our blog post tutorial on using Volume to First Responses (VFRs) from SWPM.

Adding a fourth dimension: Optimizing for heat recovery

ResFrac lends itself particularly well to the optimization of hydraulically stimulated geothermal wells. ResFrac not only computes fracturing and reservoir flow simultaneously, but also calculates thermal stress changes and supercritical fluid properties. Fowler and McClure (2021) evaluate three geothermal designs: a closed-loop, a closed-loop with thermally conductive fractures, and an open-loop multi-lateral.

Modeling unlocked 60% improvement in NPV

HFTS 2 is one of the highly measured hydraulic fracturing pads in the world. In 2021, the HFTS 2 consortia and ResFrac collaborated on a modeling study to incorporate all the advanced diagnostics in HFTS 2 into a single, comprehensive model. This model was then employed in an automated optimization workflow to assess opportunities to improve NPV by adjusting well spacing, proppant loading, fluid loading, cluster spacing, and landing zone. Pudugramam et al. presented the ResFrac model calibration and optimization in URTeC 3723620 in 2022, showing a 60% possible improvement in NPV by optimization of well placement and completion design.

Office hours recordings

Introducing ResFrac’s newest app, StageOpt

For September Office Hours, we had presentations by Egor Dontsov and Mark McClure, introducing ResFrac’s newest app, StageOpt. StageOpt calculates proppant transport from the wellbore and helps you optimize perf design to maximize the uniformity of proppant and slurry transport.

Sampling Schemes for Sensitivity Analysis

For this month’s Office Hours, we have a presentation on “Sampling Schemes for Sensitivity Analysis” by ResFrac Senior Reservoir and Completions Engineer, Chris Ponners. Chris discusses the details of the various sampling schemes provided in ResFrac’s sensitivity analysis workflows, reviews the theory and implementation of each sampling scheme, the advantages and disadvantages of different approaches, and how to pick a sampling scheme to best fit a goal of a sensitivity analysis series.
